Abstract: 962,390. Electromagnetic couplings. HEENAN & FROUDE Ltd. May 10, 1963 [Aug. 27, 1962], No. 18688/63. Heading H2A. In a liquid-cooled coupling of the type in which torque is transmitted from an inductor rotor 63 to an eddy-current drum 33 by virtue of working flux supplied by a pair of annular poles 9, 11, liquid drag in the annular air-gaps P between these poles and the outer surface of the drum is prevented, the provision of ducts 77 through the poles serving to divert liquid away from the gap. Ducts 77 may be replaced by pipes outside the machine. The cooling liquid, oil or water, enters at 69 and leaves at 73 and so passes from one end of the machine to the other. Most of the liquid is constrained by seals 31 to enter the space inside the drum where it passes between the teeth of the inductor rotor, and along ducts 75 in the eddy-current drum, if these are provided. Flooding of the machine when idle is indicated by casing vents 79. A speedcontrol generator 67 is mounted on end-plate 5. Axial flow of liquid in the rotor drum is facilitated by axial passages 81 in the rotor 63. Specifications 877,315 and 900,726 are referred to.

Abstract: 516,386. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and BOWSHER, E. A. H. June 24, 1938, No. 18799. [Class 40 (iv)] [Also in Group XXXVII] A vibrator relay adapted to oscillate at a frequency of say 50 when a magnet M is deenergized comprises a reed S fixed in a block H pivoted at P and carrying ,an arm L movable between contacts C<SP>1</SP>, C<SP>2</SP>. Energization of the magnet M attracts the reed S and causes L to engage C<SP>2</SP>. De-energization of the magnet M allows the reed to vibrate at a rate determined by its frequency, which is itself regulated by an adjustable weight W, and the arm L alternately engages contacts C<SP>1</SP>, C<SP>2</SP>. The relay is adapted for use in a toll dialling circuit, Fig. 3. When the incoming line IL is looped, a relay A closes its contacts and energizes the magnet M. On the commencement of dialling, A releases for each impulse and de-energizes the magnet M. During each de-energization the reed vibrates and the alternate engagement of the contacts C<SP>1</SP>, C<SP>2</SP> serves to charge and discharge a condenser C through the primary of a transformer T causing alternating current to be generated, in the secondary and transmitted over the toll line TL. Since each impulse commences with a movement of the reed away from the magnet and ends with a movement of the reed towards the magnet, each impulse must commence, with a positive and end with a negative half cycle so that the line and voltage conditions at the commencement of each impulse are invariable and no distortion is obtained.

Title: Method of and device for coating the cylindrical surface on the outside of rolls, especially for photo-mechanically producing printing rolls
IPC: G03F7/18
Filed: 1951-08-10
Abstract: <PICT:0709572/III/1> A method for the uniform and continuous coating of the circumferential surface of rollers, more especially printing rollers, wherein the body to be coated is arranged vertically in a receiver, the coating compound being forced into the receiver from below and afterwards drained therefrom, is characterised in that, before the compound is drained off, the drainage pipe of the receiver is closed by pinching together a flexible hose which forms part of the drainage pipe, and that for the purpose of draining off the compound the hose is released substantially instantaneously.  A roller 2 is hung inside a cylindrical reservoir 1, jacketed by an annular cavity 3 containing liquid thermostatically maintained at a desired temperature.  The roller is first surrounded by warm solvent such as water, which is then drained off and while the roller and receiver are still wet light-sensitive coating compound is forced into the reservoir 1 through a connecting socket 10 from a jacketed vessel 14 (thermostatically heated), by compressed air applied at a pipe 16. The compound is drained off, leaving a layer on the roller 2, by first tightly gripping an elastic hose 11, opening pipe 16 to the air, and suddenly releasing the hose 11.  The height of a float 15, observed through a window in the tube, indicates the velocity of drainage, which depends on viscosity, and is adjustable from one operation to another, by replacing the hose 11 with another of different bore.
